sshall a bee prescribed by documented instructions l procedures or d i 1'nd sshall a be accomplished in accordance with these instructions, procedures or drawings." Shearon Harris Specification CAR-SH-CH-6, "Concrete" states, "Each truck shall be equipped with an accurate revolution counter."

Contrary to the above, on April ll, 1979, on pour number 1WPSL236005 in the waste process building (shared by 4 units) at 6:00 p.m., the revolution counter on truck number 30 was not working.

Corrective Ste s Taken and Results Achieved:

Concrete truck was removed from service until the counter was repaired/replaced.

Counter was repaired and truck returned to service.

Corrective Ste s Taken to Avoid Further Noncom liance:

This is considered a normal failure of mechanical equipment which is handled as stated above. Drivers check trucks, including counters, before placing in service and concrete inspectors check counters as each load is delivered. Failure o counter occurred between loads and was noticed by the NRC Ins ect nspector pr ior to isc arge and prior to being inspected by the concrete inspector.

11 C m liance Will Be Achieved:

Full compliance was achieved when the counter repair was accomplished on April ll, 1979.
